[0030] See also Figure 1-3 As shown, this embodiment provides a bottom mold quick-change mechanism, including a connecting seat 1 for connecting the bottom mold, a mounting seat 2 for connecting the lifting assembly, a first magnetic member 3 provided on the connecting member seat, and a second magnetic member 4 provided on the mounting seat 2. The connecting seat 1 and the mounting seat 2 are magnetically coupled through the first magnetic member 3 and the second magnetic member 4. Figure 3 As shown, the connecting seat 1 and the mounting seat 2 are arranged along a first direction (ie Figure 3 The connecting seat 1 can be arranged on the mounting seat 2 so as to reciprocate along a first direction perpendicular to the mounting seat 2, that is, the connecting seat 1 can reciprocate along a left-right direction relative to the mounting seat 2.

[0031] See also Figure 2 As shown, a concave hole is provided at the center of the mounting seat 2, and the bottom mold quick-change mechanism further includes a limit seat 5 connected to the concave hole by bolts 7, and a through hole opened at the center of the connecting seat 1 and used for the limit seat 5 to pass upward.

[0032] A convex portion 51 is provided on the side of the limit seat 5 extending upward from the concave hole, and an annular groove 11 and a long groove 12 for the convex portion 51 to extend into are provided on the inner wall of the connecting seat 1. The axis line of the annular groove 11 and the long groove 12 are respectively parallel to the first direction, and the limit seat 5 can be disengaged from the connecting seat 1 through the long groove 12.

[0033] When the protrusion 51 of the limiting seat 5 is inserted into the annular groove 11 of the connecting seat 1, the connection between the two is relatively stable, and the bottle blowing efficiency can be ensured.

[0034] In this embodiment, the annular groove 11 and the long groove 12 intersect, the convex portion 51 can slide relative to the long groove 12 along the first direction, and the long groove 12 passes through the inner wall of the connecting seat 1 along the first direction. Through this arrangement, when disassembly is required, the connecting seat 1 only needs to be rotated so that the convex portion 51 of the limiting seat 5 enters the long groove 12, and the connecting seat 1 can be conveniently and quickly removed for replacement, which can realize rapid disassembly between the connecting seat 1 and the mounting seat 2 and rapid replacement of the bottom mold.

[0035] In this embodiment, there are at least two protrusions 51 , and the at least two protrusions 51 are evenly arranged along the circumferential direction and arranged around the outer peripheral portion of the limiting seat 5 .

[0036] See also Figure 2-3 As shown, the bottom mold quick-change mechanism also includes an elastic component 6 that is ringed between the outer peripheral portion of the limit seat 5 and the inner peripheral portion of the connecting seat 1, and the elastic component 6 and the protrusion 51 are arranged at intervals along the first direction. Through this arrangement, after mold closing, the bottom mold and the mold on the compensation gas inlet side can move toward the fixed side mold as a whole, and when the bottom mold moves relative to the lifting component for compensation, due to the flexible connection between the connecting seat 1 and the mounting seat 2 along the direction of the compensation movement, the rigid impact can be reduced and the damage to the connection structure between the two can be avoided; the bottom mold quick-change mechanism can support the bottom mold to move in any direction within the plane perpendicular to the first direction to perform mold closing compensation; after bottle blowing is completed, the connecting seat 1 is reset under the coupling of magnetic lines of force, and the reset dead zone caused by friction between the first magnetic part 3 and the second magnetic part 4 is eliminated by the elastic restoring force provided by the squeezed elastic component 6, so as to facilitate smooth mold opening; at the same time, this flexible connection can reduce vibration and noise, and is conducive to the smooth and efficient operation of the whole machine.

[0037] In this embodiment, the elastic component 6 includes an elastic O-ring 61 that is disposed between the outer periphery of the limiting seat 5 and the inner periphery of the connecting seat 1 , and at least two arc-shaped members 62 that are disposed inside or outside the O-ring 61 .

[0038] In this embodiment, a mounting groove for mounting the O-ring 61 is recessed on the outer peripheral portion of the limiting seat 5 , and there are three arc-shaped members 62 , which are arranged on the outer side of the O-ring 61 along the circumferential direction.

[0039] See also Figure 2 As shown, there are a plurality of first magnetic members 3, which are evenly arranged along the circumferential direction and arranged around the outside of the through hole; correspondingly, there are also a plurality of second magnetic members 4, which are evenly arranged along the circumferential direction and arranged around the outside of the limit seat 5. In this embodiment, the plurality of first magnetic members 3 and the plurality of second magnetic members 4 are aligned one by one along the first direction.

[0040] The working process of this embodiment is described in detail below:

[0041] After mold closing, compensation gas is introduced into one side of the mold, so that the mold on this side and the bottom mold move synchronously to the other side, and the connecting seat 1 moves synchronously relative to the mounting seat 2 until the mold closing compensation is completed, at which time the O-ring 61 is further squeezed and deformed;

[0042] After bottle blowing is completed, the supply of compensation gas is stopped. Under the action of magnetic line coupling, the connecting seat 1 is reset relative to the mounting seat 2. The reset dead zone between the two is eliminated by the rebound O-ring 61, so that the connecting seat 1 is completely reset relative to the mounting seat 2.

[0043] When the bottom mold needs to be replaced, the connecting seat 1 is rotated to allow the protrusion 51 of the limiting seat 5 to enter the long groove 12, and the connecting seat 1 is pulled out upwards to quickly replace it.
